What preamp?

I have just purchased a ARC Vt-100mk2 and now know that my tubed preamp Quicksilver is my weakest link in my system. I am looking for VT-100 mk2 owners, what preamps work with this amp? Tube or SS?

System:
VT 100mk2
Quicksiler Fulfunction pre
Tyler Acoustic Lynbrook Sign. monitor
EMC MK2 CD player
Nordost Blue Heaven Speaker & IC's
